Which of the following ocean-floor features would contain the newest rocks?

2 answers:

7 0

The further away from the mid-ocean ridge, the older the rocks are on the ocean floor. Therefore, the ocean floor feature that would contain the newest rocks would be the mid-ocean ridge.

Answer: Mid-ocean ridge

A mid-ocean ridge is an underwater mountain landmass generated after the plate tectonics. It forms when the ocean floor is uplifted by the magma generated by the rise of convection current during the divergent plate tectonics. The rocks generated by this process is due to the solidification of the lava after underwater volcanic eruption. Therefore, mid-ocean ridge likely to form new rocks in the oceanic bed.

Do some research on digital vs. analog recording, and decide which you think gives the most accurate and best quality sound. Sta

rodikova [14]

Answer:

Sound quality depends on a lot of factors, and it is impossible to definitively state that either analog or digital is fundamentally better. These days, many records are made using playback of a digital file, so vinyl preference cannot be attributed solely to the differences in the way the sound wave is reproduced.

Which statement explains how it is possible to carry books to school without changing the kinetic or potential energy of the boo

Mamont248 [21]

Answer:

a. by moving the book without acceleration and keeping the height of the book constant

Explanation:

FOR CONSTANT KINETIC ENERGY:

The kinetic energy of a body depends upon its speed according to its formula:

ΔK.E = (1/2)mΔv²

So, for Δv = 0 m/s

ΔK.E = 0 J

So, for keeping kinetic energy constant, the books must be moved at constant speed without acceleration.

FOR CONSTANT POTENTIAL ENERGY:

The potential energy of a body depends upon its height according to its formula:

ΔP.E = mgΔh

So, for Δh = 0 m/s

ΔP.E = 0 J

So, for keeping potential energy constant, the books must be moved at constant height.

So, the correct option is:

<u>a. by moving the book without acceleration and keeping the height of the book constant</u>
